FOUNDATION OF C'ARDnCLOTHlNG.

SPECIFICATION forming part of Letters Patent No. 397,441, dated February5, 1889.

Application tiled January 18, 1888. Serial No. 261,133. (No model.)Patented in England February 22, 1887, No. 2,727.

To (LZZ whom it 71mg/ concern..-

Be it known that I, SQUIRE ROBER'ls, a subject of' the Queen of GreatBritain and Ireland, and residingl at (lleckheaton, in the county otYork, England, have invented certain lmp royements in the Foundations ofCard-tliotlr ing' for Carding Fibers, (for which l, along with myassignees, .Henry Law and John Vosper Curry, have obtained LettersPatent in England, No. 2,727, dated February 22, $87,) of which the'following is a specification.

This invention relates to certain improvements in the construction ol'the foundations for card-clothing which are now commonly employed inlieu of leather Formerlyusedtor this purpose, the nreat cost ot leatherand its inequality as to thickness and pliability leading,l to theadoption ot a woven fabric coated with rubber and now universally knownas clotli-Iilletinm but ex] erience has shown that whereascloth-tilleting' has many advantages over leatln-nr, itv neverthelesshas one radical defect, which is the object of this invention to remedy,and thatis that aft-erbeing worked a time the foundation elongates andbecomes slack on the surface of the card-cylinder, thereby causing whatis technically known as running the result beine; bad cardine,` orinferior opening' oi' the fiber, and considerably sllortening the lifeof the whole of the clothing of the card.

In the accompanying sheet ot drawings, Figure l represents the underside of a piece of card illeting constructed according to thisinvention, showing a fewn oi the crowns ot' the dents or teeth A, whichare inserted in the ordinary manner; and Fig'. 2 is a cross-section ofthe same drawn to an enlarged scale, the teeth or dents A being on theupper surface.

vThe card foundation may be composed of two or more thicknesses of clothand rubber, the drawings illustrating' a card foundation composed of twosheets of cloth of strong;l texture, indicated by the lettersB and C,and a coveringI of sheet-rubber, D, the latter and cloth B beingcemented together in the usual manner, and in order to provide apositive remedy At'or the before-mentioned well-known serious detect anumber of metallic wi res,W, are placed lengthwise, by preference,between the iwo sheets of cloth B and G,which are also cemented togetherin the same manner as hitherto, thereby embeddingl in the foundationpliable material practically no11elastic,whieh acts as a metallic warp,greatly adding to the strength of the cloth, and absolutely preventing,`the elongation or running, as is the case with clothingas hithertoconstructed after being in use for a short time.

I am aware that it has been proposed to con'ibine metallic warps orstrips with beltingx or hose; but

l claim as my invention- Oloth-iilleting,l of rubber and cloth withlongitudinal metallic wires between the layers and with card teeth ordents passing,` through this lilleting, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribi n witnesses.

SQ'UIRE ROBERTS.
